How Do I Put a 5834-4 Into High Security Mode?

You can put a 5834-4 into high security mode by pressing and holding its top-left button, its bottom-left button and its bottom-right button all at the same time. Each button must be held for five seconds. The LED light will flash red to indicate that high-security mode has been entered.

There are two main modes for a Honeywell 5834-4 Key Fob. These are low-security mode and high-security mode. Low-security mode just has the key fob operate as a plain uni-directional sensor. The key fob will send a one-way command to the panel. The panel will recognize the key fob signal, and the command will go through. This is the same way that most of the sensors in the Honeywell 5800 Series operate.

High-security mode is a little more complicated. In this mode, the key fob sends an encrypted signal to the panel. The key fob must then receive a return signal from the panel that confirms that the secured device sent the original signal. The encrypted key fob will confirm this, and the command will then go through. This "digital handshake" adds an additional layer of security, and it prevents intruders from hacking into the system with a phony key fob.

The reason why a user might not want to use high-security mode is because the key fob can be a little more difficult to program. The key fob will need to be synced with the panel for it to work in high security mode. Only the Honeywell LYNX Touch Panels and Honeywell VISTA Panels can support the key fob in high-security mode. When using high-security mode, the key fob can only be programmed with one panel. This is not the case with low-security mode, where you can actually use the same 5834-4 Key Fob with multiple alarm systems.

The way to differentiate between low-security mode and high-security mode is the color of the LED light on the sensor. In low-security mode, all LED flashes are green. In high-security mode, all LED flashes are red. You can toggle between the modes by pressing and holding three distinct buttons on the device. Both low-security mode and high-security mode have their own unique set of three buttons.

For entering low-security mode, the B, C and D buttons are used. The LED will flash green to indicate that low-security mode has been entered. For entering high-security mode, the A, C and D buttons are used. The LED will flash red to indicate that high-security mode has been entered. The buttons must be pressed simultaneously and held down for five full seconds for this this to work. The table below shows the buttons on the 5834-4 Key Fob:


To reiterate, high-security mode uses the top-left, bottom-left and bottom-right buttons. By default, these are the Arm Away, Arm Stay and Auxiliary Panic buttons. The buttons must be pressed and held for five seconds to enter high-security mode. Low-security mode uses the top-right, bottom-left and bottom-right buttons. By default, these are the Disarm, Arm Stay and Auxiliary Panic buttons. The buttons must be pressed and held for five seconds to enter low-security mode.

Please note that you may experience trouble using your 5834-4 Key Fob in high security mode if you have not synced the key fob with the panel. This is an added security function that allows the key fob and panel to share the same rolling encryption code. Many users will try to use the key fob in high-security mode, only to find that the panel does not respond to their commands. The most likely cause is that they have not properly synced the key fob with the panel. For more information on syncing a 5834-4 Key Fob with a LYNX Touch or VISTA Panel, please see this helpful FAQ. Remember, high-security mode will only work with a LYNX Touch or VISTA Panel. Additionally, a 5834-4 in high-security mode can only be used with a single alarm system.

If you want to put your 5834-4 Key Fob into high-security mode, complete the following steps:

1. Check the current mode. Press and hold a single key fob button. Check the LED color. If the LED light is red, then your 5834-4 Key Fob is already in high-security mode. You can stop here. But if it flashes green, then your 5834-4 is in low-security mode. You can continue to the next step.

2. Access high-security mode. Press and hold the A, C and D buttons in the diagram shown above. These are the upper-left, bottom-left, and bottom-right buttons respectively. If you prefer identifying these buttons by pictures, they are one with the locked lock, the one with the guy standing inside a house with a red star next to it, and the one with the big red star. If you prefer remember the default names for these buttons, they are the Arm Away button, the Arm Stay button, and the Auxiliary Panic button. Regardless of how you personally identify these buttons, you will want to press and hold them for five (5) seconds. You might want to use both hands to make this easier. Keep them held down until the LED light flashes red. This indicates that high-security mode has been entered.

3. Confirm high-security mode. Press and hold a single button on the key fob. Check the LED color. If the LED light is red, then you have successfully entered high-security mode. Congratulations! But if the LED light is green, then you did not complete Step 2 correctly. Please go back to Step 2 and try again.
